Literal-minded is a term used to describe someone who takes everything at face value and has trouble understanding metaphors or sarcasm. Other synonyms for this term include concrete thinking, unimaginative, rigid, inflexible, and uncreative. Some people may also describe this person as being humorless or lacking in imagination. These individuals tend to focus on the details and may struggle to see the big picture or take a more abstract approach to problem-solving. However, literal-mindedness can also be beneficial in situations where clear and concise communication is required. It is important to recognize that everyone has different thinking styles and strengths, and literal-mindedness should not be viewed as a negative trait.
